T0 aZZ whom it may concern:

Be it known that W8,MINNIAFFEE J. JARDEE and ROBERT J. CownLL, citizens of the United States, residing at St. Jose h, county of Buchanan and State of Missouri, have invented certain new and useful Tmprovements in Oil Burners, of which the following is a specification.

Our invention relates to new and useful improvements in oil burners and one object is to provide burner in which refined petroleum can be economically'employed as a fuel.

Another object is to soform the burner that the combustible mixture shall be evenly distributed throughout said burner so that when ignited it will heat the burner uniformly throughout without superheating certain portions thereof.

A further object is to provide means for preventing the unconsumed portion of the gas in the generator when the same is shut off to extinguish the flame, from giving off offensive odors which ordinarily arise from such unconsumed gas when the burner is again lighted. v

A further object is to provide a burner generator with a dust collector in which the foreign before they can reach and choke the discharge port.

Other objects will hereinafter appear, and

in order that the invention may be fully understood, reference will now be had to the accompanying drawing, in which:

Fig. 1 is a plan view of the burner with a portion of its generator broken away.

Fig. 2 is a side elevation.

Fig. 8 is an enlarged vertical section through the rear portion of the burner and its mixing chamber.

Fig. 4 is an enlarged horizontal section of a portion of the burner generator taken on line IV-IV of Fig. 2.

Referring now in detail to the various parts, 2 designates the body of the burner whichis substantially rectangular incontour. The upper wall t of the burner is highest at its center as indicated at 6 from which it slopes towards its front and rear ends 8 and 10, respectively, the slope being greater towards the front end in order to correspondingly reduce the inside area of the burner.

The upper and side walls of the burner in the machine screws 15.

have saw cuts or slits 12 for the escape of the walls of the burner are, preferably, cast integral and the rear wall is equipped with a supplemental wall 14 which is removably secured in place 'by suitable means such as vided with an integral mixing chamber 16, the inlet end 18 of which is spaced from the rear wall 15, so that airmay be readily drawn therein by the suction of the gas as it is ex- -pelled from the discharge nozzle 20:01:" the generator 22. The lower end of the mixing chamber 16 is slightlyicontracted and communicates with-an inlet 21 and the rear wall of the burner 2 into which the combustible mixture is discharged. v v

The upper wall t of the burner body 2 has a trough 26 extending longitudinally The wall 14 is pro-L thereof to receive noncombustible absorbent 7 material such as'asbestos wool, which on be ing saturated with alcohol or other inflammable liquid, will ignite and produce a flame sufiicient to initially start the generation into gas of the liquid fuel in the generator 22.

The generator 22 is supported just above the upper wall 1 of the burner 2 by a saddle 30, formed integral with the upper front portion of the burner, and the supplemental wall 14:, which has an opening 32 to receive the forward end of said generator 22.

The generator 22 consists of a tube 34: and a goose-neck 36 threaded or otherwise secured to the rear end of said tube 34. The

goose-neck 36 is provided with a rearward 7 extension 38 equipped at its rear endflwith the discharge nozzle 20, which is supported in alincment withthe inlet 18 of the mixing chamber 16. The goose-neck 36 is also providedwith a lateral extension 40 in which a dust collector 4:2 is threaded and adapted to intercept foreign matter which would otherwise choke the discharge nozzle 20. As disclosed by Fig l, said dust collector'4l2 projects "inwardly beyond the extension 38 and has small perforations 44:

I which permit the generated gas to pass freely to the discharge nozzle 20 but intercept bore of; the

carbon and other foreign'matter which is carried back into a chamber 46, where 1t acj cuinulates until the dust collector 4-2 is removed and cleaned. As a further precautionary measure to prevent the nozzle 20 from becoming choked, I provide the exten- -sions 38 with a fine mesh screen50, to interintegral with the shell of a drain valve 58 through which the 'unconsumed gas in the generator 22 may be drained oil", the tube34l the process orgenerating the oil into gas sloping downwardly its forward end for that purpose.

In order'to start the burner the material in the trough 26 is ignited to heat the generator 22, after which-the needle valve 52 is opened to allow the oil to pass into the heated generator where it is formed into agas which escapes through the discharge nozzle 2-2 with sufiicientrorce to pass through the anixing chamber 16 and drawing air therewith enter the body 2 or the burner, -through the jslits l2 or which it escapes and is ignited. The flame thus produced heats the burner 2 and the generator 22, so that will continue until the supply or" oil is cut off. The coinbustible mixture expands as it enters the heated burner body 2, the greatest expansion occurring approximately within the'central portion or the burner, and to a less degree at its rear end, and a lesser de 'ygree at its forward end, the peculiar shape of the top wallet compensating for these difi'erences in pressure, with the result that the combustible mixture issues at an even pressure, or'approxim'ately so, from all of the slits l2, and on becoming ignited as above stated, uniformly heats'the burner instead oi t'superheating' certain portions thereof and causing irregular expansion and con- -'traction which would eventually result in the destruction of the body portion 2.

From the foregoing description it will be readily understood that we have provided a burner and a generator embodying the advantages above set forth, and while we have shown and described the preferred construction, combination and arrangement we claim and desire to secure by Letters m Patent, is:

1. In a device of thecharacter described,

a burner body tapering towards its ends and having openings therein for the escape ofa combustible mixture, a rear wall removably securedto said burner body, curved mixing chamber supported by said rear wall, the upper intake end of said, mixing chamber being spaced from the rear wall while the loweror discharge end or said mixing chamber terminates flush with said rear wall and communicates with the rear portion or the body to discharge the combustible mixture into saidbody, a generator provided with a goose neck and extending longitudinally of the burner body and ranged to discharge into the intake of the mixing chamber, and a trough extending longitudinally. of the burner body and beneath said generator for the purpose described.

2. In a device or the character described,

neck fixed to said tube and provided with rearward and lateral extensions, adischarge nozzle fitted to the rearward extension, and a tubular dust collector'closed at its outer a generator consisting or a 13L1b6, 2L'g0OS61 V end and having its open inner end project;

ing into the lateral extension. 7

3. In QUE-V106 or the character described, a generator cons sting of a tube, a gooseneck fixed to said tube and provided with rearward and lateral extensions, adischarge nozzle fitted to the rearward extension, a screen within the rearward extension, and a perforated dust collector closed at itsouter end and removably fitted at its 'open inner end into the lateral f stension.

In testimony whereof we our signatures, in the presence 'of two witnesses.
